Clamps can be stacked for increased holding power.

For use with STC & STC-VP Series Clamps.

Mechanism

BTM's patented Tri-Lok® mechanism is a three point lock which remains engaged even if air pressure is lost. In addition to locking, the mechanism also provides accurate arm position and repeatability. Clamps equipped with Tri-Lok® are ideal for use in clamping, or as a backup.

The exclusive Tri-Lok mechanism removes all working tolerances from all moving parts to provide a very repeatable (+/- 15') and rigid closed arm position. This unique arrangement is highly resistant to torque coming from force applied to the clamp arm.
